The skincare market offers an abundance of products that benefit the skin. However, TikTok users often aren't satisfied until they can put their spin on a product or even create it themselves. Across the app, skincare has an accumulated total of 65B views. Whether it's a traditional routine accredited by a dermatologist or a questionable craze, one thing's for sure: the videos keep coming. Here are the skincare trends rising in popularity on TikTok, selected by BeautyMatter.

Menstrual Face Masks

This month, face masks are the DIY go-to, now with a menstrual twist. Users are making the most of their cycle, adding period blood to their faces to achieve an extremely natural glow. The trend is what it says on the tin, and according to @sacredunveiling, a popular user affiliated with the craze, the mask adds moisture to the skin and aids in preventing blemishes while helping to connect with one's femininity.

However, it seems that the trend has not risen to fame for its benefits, but instead due to how many disagree with this self-care practice. Several TikTok dermatologists, as well as everyday app users, have responded to those taking part, expressing their discomfort. @Teawithmd, aka Dr. Joyce, a popular dermatologist on the app, created a video addressing the situation, pleading with her followers, "I beg of you do not use your period blood as a face mask; there is no way you're collecting that blood in a sterile way." The doctor then explains that doing so is potentially very harmful as sweat and bacteria live in menstrual blood, and the damage could be severe for those who may be unaware they have infections or STDs.

According to another dermatologist on the app, Dr. Karan Raj (@dr.karanr), using blood to achieve more youthful-looking skin originated centuries ago, in 1600, when Countess Elizabeth Báthory bathed in the blood of hundreds of women and girls she murdered to produce a younger look. Not surprisingly, there is little to no evidence that Countess Báthory’s methods worked, nor that using menstrual blood as a face mask reaps any benefits. However, it is suggested that if people wish to use their blood to soothe their skin, they should seek professional practices, such as platelet-rich plasma facials, that correctly extract beneficial elements of blood from the body.

Skin Cycling

A skincare trend that dermatologists are far more inclined to support, skin cycling is the concept of applying active ingredients only on certain days, following them up with rest days. Across the app, a four-day cycle is the most popular course of time, which consists of using two active ingredients across two nights, followed by two nights of rest, and then repeating the process. The trend has now received over 3.5B views and has been supported by several professionals and fans alike.

The top-liked video under the skin cycling tag comes from @justsomechick, who guides her followers through a cheat sheet for skin cycling. The video, which has received 440.4K views, instructs followers to approach the trend starting with the basics—cleanser, serum, moisturizer, and oil, instructing them to stick to the routine strictly. Users are clearly appreciative of the video, with one comment reading: "The public requires you to never delete this post for scientific purposes."

Another popular video off the back of the trend comes from @kayli.boyle, who shows the results of her skin cycling after two months of practice. Within the video, Kayli shows pictures of her skin before cycling when she suffered from cystic acne, and at the end of the video, she showcases her completely clear skin, thanks to the trend. The post has received 26.6K likes and encouraged several other users to undergo the process, showing off their results on the app, proving that for many, the cycle is a positive one with hugely effective results.

Micellar Water Activation

A trend that was popular back in 2018 when TikTok was named Musical.ly has bubbled back up to the surface of app users' minds—turning micellar water into a bubble-like cleanser. The video that saw the hype resurface came from @saragomez13, who has received over 1.1MM views on her post. In the video, Gomez takes a cotton pad and saturates it with micellar water, and then puts the pad to her lips and blows into it, causing the water to activate into bubbles.

In response to Sara's post, influencer Meredith Duxbury tried the trend and went on to cleanse her face with the bubbles, and received 922.4K likes. However, as expected with any skincare trend that finds its way to TikTok, dermatologists on the app have had their say. In a video that received 37.2K likes, dermatologist Dr. Adel compares regular usage of the product to the activated version. In conclusion, the dermatologist states that regular micellar water use works more effectively and removes more makeup, dubbing the activation trend as something that should just be done for fun.

Other users are more concerned about the logistics of the trend, with one user commenting, "Surely you're just putting bacteria from your mouth all across your skin?" The comment received over 13.4K likes, showing that despite TikTok users adopting some pretty strange trends, the app has taught them a thing or two about what is and isn't good for the skin.

Skin Taping

Described as a DIY facelift, skin taping is a technique said to significantly reduce the appearance of wrinkles over a few weeks. Previously reserved to the likes of drag queens and professional makeup artists, the trend soared to popularity when @joe.drummer.boy, aka John Moody, who gives "insights for life," took to the app to share his secret, instructing his followers to apply tape to areas of the skin with wrinkles, lifting the skin in the process. Many have tried the trend, including @theaussierapunzel, who claims she saw results within four days.

In Moody's video, the TikToker can be heard saying, "The doctors and the advertisers will not tell you about this one because they can't make any money off of it." Dermatologist Mamina Turegano posted a response video, telling her followers that many derms do, in fact, want to help their clients find cheaper ways to achieve their goals; however, skin taping is not the quickest way to achieve anti-aging effects. Turegano then goes on to explain that although the technique is not the fastest way to reduce wrinkles, there is evidence that the trend reduces skin stress and promotes blood circulation which, in the long term, prevents age-defining marks from showing.

In the comments, many shared their opinions, with some explaining the hack is actually called tapotement and goes far back in the industry, with many learning the benefits when studying at beauty school. Thousands of users have attempted the technique, but the overall champion of the trend is @chloewaterz, who received 8.4MM likes for her reenactment of the skincare craze.
